在OpenVPN有两种连接方法。TUN Device and TAP Device
从【1】，
TUN Device： A TUN device is a virtual point-to-point IP link.
TAP Device： A TAP device is a virtual ethernet adapter.
从【2】，
TUN (as in network TUNnel) simulates a network layer device and it operates with layer 3 packets such as IP packets. TUN is used with routing.
TAP (as in network tap) simulates a link layer device and it operates with layer 2 packets such as Ethernet frames. TAP is used to create a network bridge.
